[Qemu-devel] [PATCH v4 1/2] pcie: Add a simple PCIe ACS (Access Control Services) helper function

2019-02-13 Thread Knut Omang
Add a helper function to add PCIe capability for Access Control Services (ACS) ACS support in the associated root port is needed to pass through individual functions of a device to different VMs with VFIO without Alex Williamson's pcie_acs_override kernel patch or similar in the guest. Single
